TapeXray alternatives: arbitrage scanners compared (2026)

A few products scan Kalshi and Polymarket for cross-venue gaps. This page compares TapeXray against the ones with a public pricing or product page this desk could actually read and cite — not a ranked “best of” list, and not a claim that TapeXray is cheaper. Every figure on either side below is sourced: ours from the live export, theirs from their own page, dated.

Why so few?

A third name that came up in early research, PolyArb, could not be confirmed as a live product with a checkable page, so it is not compared here. A comparison page that names a product without a page to cite would be exactly the kind of unverifiable claim this site exists to avoid making about itself. If that changes, this page will too.
